core, lib, modules: restructured source code tree

- new folder src/ to hold the source code for main project applications
- main.c is in src/
- all core files are subfolder are in src/core/
- modules are in src/modules/
- libs are in src/lib/
- application Makefiles are in src/
- application binary is built in src/ (src/kamailio)

- atomic_add & atomic_cmpxchg added to ppc - atomic_unkown (used when the procesor does not suport atomic ops or is not among the supported ones), tries now to use a "hash" of locks if GEN_LOCK_SET_T_UNLIMITED is defined => less contention on multi-cpus - atomic_ops.h defines *_UNLIMITED macros when the number of locks or set size are limited only by the available memory (everything exept SYSV sems) - license changes: all the atomic* stuff and the locks are now under a BSD (OpenBSD) style license

- makefile: - compile in 64bit mode by default on sparc64 - sparc <= v8 support - -CC_GCC_LIKE_ASM is defined when the compiler supports gcc style inline asm (gcc and icc)

- atomic operations and memory barriers support for:
- x86
- x86_64
- mips (only in NOSMP mode and if it supports ll and sc)
- mips2 (mips32, isa >= 2)
- mips64
- powerpc
- powerpc64
- sparc <= v8 (only memory barriers, the atomic operations are implemented
using locks because there is no hardware support for them)
- sparc64 - both 32 (v8plus) and 64 bit mode
If there is no support for the compiler/arch. combination, it falls back to
locks.

The code is tested (only basic tests: it runs and the results are ok, but no
parallel tests) on x86, x86_64, mips2, powerpc, sparc64 (both modes).
The sparc version runs ok on sparc64 (so it's most likely ok).
powerpc64 and mips64 not tested due to no access to the corresponding
hardware, but they do compile ok.
For more details see the comments at the beginning of atomic_ops.h.
